Hi Michael, List,
I apologize for re-sending the message, and now responding to my own not your
reply. My initial message was sent when I was not subscribed to the list. I was
looking at the archive website and did not see it show up there (I was looking
in the wrong place) so I subscribed and re-sent. Hence it appearing 2x. I'm now
subscribed and should see replies and be able to reply to them properly.
ulimit -Hn and -Sn both report 32768, so that's not it.

$ cat /proc/sys/fs/file-max

Also seen at
$ cat /proc/sys/fs/file-nr

Seems reasonable so far, and nothing obvious (to me) in dmesg.
journalctl shows tons of errors (OpenGL, X11 even though I'm on Wayland, Qt,
etc.) and shows it occurring more than the few times I see it from some
terminal commands that I run. But nothing is crashing because of it as far as I
can tell.

Dolphin still opens.

Tail still works.
Your suggestion to look at /proc/*/limits shows:
$ cat /proc/[0-9]*/limits 2>>/dev/null | sed -ne '1p;/^Max open files/p' | sort
| uniq -c | sed -e 's/ *$//;s/ //' | sort -k 5bn
1 Limit Soft Limit Hard Limit Units
1 Max open files 50 50 files
268 Max open files 1024 4096 files
29 Max open files 1024 524288 files
100 Max open files 4096 524288 files
6 Max open files 8192 524288 files
22 Max open files 32768 32768 files
1 Max open files 65535 524288 files
19 Max open files 65536 524288 files
3 Max open files 65536 65536 files
2 Max open files 131072 131072 files
5 Max open files 524287 524288 files
29 Max open files 524288 524288 files
17 Max open files 1000000 1000000 files
3 Max open files 1073741816 1073741816 files
Looking at that last line:
$ grep 1073741816 /proc/[0-9]*/limits
/proc/1644/limits:Max open files 1073741816 1073741816
files
/proc/1/limits:Max open files 1073741816 1073741816
files
/proc/770/limits:Max open files 1073741816 1073741816
files
$ ps aux | grep -E " 1644 | 770 "

But I'm not sure what to do with this information...
Thanks for your help so far,
-k.
